As I referenced in another discussion, I bought (6 years ago) a P/N WPW10361353, which is a square shape for a Cabrio/Bravos. I traced one of the direct-drive pads I had on-hand onto a piece of cardboard for a template to cut the Bravos pad accordingly.
WPW10361353 is also NLA. They're not crucial mechanical operational parts so go NLA somewhat quickly.
These pads are soft, not rigid/hard.
